BOOKBINDER S CASE GAUGE INVENTOR Patented Nov. 19, 1935 PATENT OFFICEBOOKBINDER S CASE GAUGE Walter John William Wilson, Victoria, BritishColumbia, Canadal Application January 8, 1934, Serial No. 705,832 InCanada April 8, 1933 10 Claims.

. art which has hitherto, to a very larger extent, partaken of thenature of one of the strict hand-` crafts, has naturally been confrontedwith corresponding difficulties when mass production of books has beencalled for, and an object of this invention has been to greatly increasethe rapidity of afxing and securing cases (or book covers) and also withmuch greater precision and exn actitude than has hitherto beenpracticable with the slower hand processes.

The invention resides in the novel combination and arrangement of parts,as fully described herein with the aid of the drawing which accompaniesand forms a part of this application, and in which Fig. 1 is a plan viewof the device,

Fig. 2 is a longitudinal elevation on line 2.-.2 of Fig. 1 and Fig. 3 across sectional elevation on line 3 3 of Fig. 1.

The drawing indicates one preferred embodiment of the invention, but isnot intended to be limitative as regards precise details of constructionexcept as such may fall within the language and the scope of the claims.

It will be observed that the device is in table form, the top surfaceplate or table proper being divided transversely into two portions so asto leave a rectangular recess between'them for the reception of the backstrips.

The width of this recess is made adjustable by longitudinal movement ofone half of the table top. This back strip recess is alsoadjustable,longitudinally and is provided with a suitable vertical feeddevice for the lproper presentation of the strips.

A variety of other adjustments and devices in connection with thereception and manipulation of the boards, cloth, and other elementsconcerned are arranged adjacent the table surface and are morespecifically referred toas the description workof a. rectangular tablewhich maybe constructed in any convenient manner as withverticaliangle-.irons to for-m the corner uprights, secured in anyconvenient and usual manner to make .,a. rigid support. for thehorizontal table plates l and 8, the former being the xed portionthereof. The adjustable portion 8 of the rectangular table is securelyheld in any desired position by transverse bolt 41 and wing nut 48 whichoperating through the framework 3 causes the latter to securely gripstrips or projections 49 aixed to the under side of the adjustable tableplate. Slidable transversely over the top surface 5 of the table plates'l and 8 is the rectangular cross-sectional fiat guide bar 9 againstwhich the top edge of the boo-k boards are abutted. This guide bar isactuated and adjusted by the revolvable screw I0 which engages the nut H10 traversing the screw I0 and the longitudinal guide slot l2 in the topof the table l.

The additional guide slots I3 which are engaged by correspondingprojections on the lower side of the guide bar 9 provide the necessaryl5.

restraining action to the latter and insure its parallel movement.

Removable clamping gauges I4 provide a ready means for adjusting the topgauge I5'and are secured to each half of the table top l and 8 20 byclamp screw I6. On the outer portion of each half of the table top areside gauges Il which are traversed longitudinally in the parallel slotsI8 and actuated therein by the screw and nut device below them which isadjustable by the 25 milled hand-wheels 20. Joint gauges for positioningthe back boards in relation to the back strips are provided at 2 I. Thestops which constitute the joint gauges are slidable in the short slots`22 and actuated longitudinally therein by 30 nut and screw device belowthem, the screw member thereof 23 being actuated by revolution of thesmall milled hand-wheel 24 within lthe slot 25 and immediately below thesurface of the table top land 8.

The back strip recess 26 is a salient feature of the device. 'I'he walls2l of this recess ar-e each secured to their respective portions of thetable tops 'l and 8 and between them is a vertically slidable tableconstruction 28 supported by 40 the telescopic support 29 the lowertubular member of which is secured to and supported by the flat platemember 30.

Slightly above the plate 3B is a similar plate 3|, between this memberand the table 28 and at 45 each -end thereof are vertical springs 32which afford the slight upward thrust required for automatically feedingthe back strips upwardly as they aremade use of. This lifting effect isfurther regulated or adjusted by a hand lever 33 50 which is fulorumedat 43 and at its opposite end projects conveniently beyond the end ofthe table framework, and is .adapted to engage a ratchet bar 34. Thislever..33"which is .conveniently Ormed of a flat bar is twisted at itscentre 35 6 5 so that its flat surfaces are horizontal where theyconnect to the spring supporting plate 3 lV through a springend boltattachment 36.

A backV strip longitudinal adjustment is provided at 31 andV consists ofa bracket 38 secured to the' framework 6 and carrying a movable plate 3Ssecured to the screw mand the pin guides :il horizontally movable in thebracketY 38. The screw k40 is reciprocated by the restrained hand nut 42which its thread engages.

A further longitudinal adjustment to the back strip is provided at'theopposite end thereof and consists of a short flat plate I3 having anabrupt downturned end and positioned and slidable against the undersideof the flat gauge plate 9,

each of the plates'43 and 9 having alongitudinal Y' slot Mand'irespectively and the two slots being right angularly disposed to eachother and secured in any desired relation by the screw boltV 56, so thatin addition to the longitudinal adjustment there is a transverseadjustment whereby a very narrowY back strip may be promptly allowedfor. By these two independent longitudinal adjustments a gauge-stop isprovided at each end of the back. strip.

In operation the case gauge is adjusted and Set in all its particularsto conform with the speciiications of the required cases, and in furtherpreparation a sufficient quantity of back strips are then placed in theback strip recessV 2G and on the carriage 28.

Two boards are then placed flat on the table 'l and 8 with their edgesrespectively tting loe- Y tween and abutting on the ilat guide bar s,side horizontal table, said table being divided trans-VV versely intotwo portions, one being slidable from or towards the other andadjustable in any desired position whereby a relatively narrowrectangular recess is provided between the two said portions of thetable top, said recess being adapted to receive back strips.
